SAYI YMF PM variable-speed screw — model-specific 8 bar duty — SAYI (Wenling works)

Datasheet

Product overview

Power: YMF examples:7.5–37 kW · Pressure: Selected table rows:8 bar · Flow: YMF table:1.05–6.3 m³/min;basis to confirm

The official Y-series permanent-magnet variable-speed single-stage screw page identifies YMF rows separately from the company's Y fixed-speed page. Its starting-method column explicitly describes permanent-magnet variable-frequency control. Specify the complete YMF code; the broad Y-series name does not establish the drive of every Y machine.

At the table's 8 bar condition, YMF8-8 gives 7.5 kW and 1.05 m³/min; YMF11-8 gives 11 kW and 1.7; YMF15-8 gives 15 kW and 2.2; YMF22-8 gives 22 kW and 3.3; YMF37-8 gives 37 kW and 6.3 m³/min. These are manufacturer volume-flow values, not an independently established FAD test result. Confirm pressure convention, inlet/reference conditions and offered performance.

YMF8-8 has G3/4 outlet, 930 × 680 × 916 mm and 190 kg. YMF11-8 and YMF15-8 share 1010 × 770 × 1033 mm and G3/4 outlet but weigh 250 and 270 kg respectively. YMF22-8 has G1 outlet, 1200 × 820 × 1150 mm and 370 kg. YMF37-8 has G1½ outlet, 1370 × 950 × 1360 mm and 560 kg. Ask for installation/service clearance and shipment dimensions separately from these package envelopes.

Give required point-of-use pressure, network losses, average/peak consumption, flow basis, shifts and electrical supply. Request selected-model capacity and package input across the permitted speed/load range, minimum stable demand, stop/start behaviour and actual ambient/cooling limits. A general energy-saving or quiet-operation description is not a quantified comparison or acoustic test.

Agree air-end lubrication and delivered air quality, receiver/dryer/filters, condensate handling, protection/interlocks, maintenance access and consumables. Obtain performance, package and electrical drawings, manuals, acceptance tests, commissioning and warranty/destination-support terms. The original photograph is the Y PM page's family machine example; it does not identify every tabulated model or every included auxiliary.
